Reflection: Energy - The Fuel of the Universe

"Hubble Ultra Deep Field"

A look back in time nearer to the "Big Bang" 

According to the commonly accepted theory of the big bang, approximately 13.73 ± 0.12 billion years ago, the universe started expanding from an infinitesimally small point into the visible universe that we know of today, over 93 billion light years wide. After one Planck time (about 5.39124*10^(-44) seconds), gravity separated from the electronuclear force. After one picosecond (1.00*10^(-12) seconds), the “weak” force separated from the electromagnetic force resulting in the four forces we know today. By one hour, helium nuclei formed. In 370,000 years, hydrogen and helium nuclei captured electrons and formed stable atoms. By 100 million years after the big bang, the first stars began to shine. It may seem surprising, but all of the energy in our universe at this moment, was present from the very beginning. Some of what I have learned during this unit about energy is explained in the following "Glog":

Physics Carol

In this glog is the lyrics for a song "Wondrous Physicsland" written by me, sung to the tune of "Winter Wonderland."  I hope that you enjoy!

PS: I also wrote a short carol entitled "Hark - Newton's Second Law of Motion" written by me, sung to the tune of "Hark the Herald Angels Sing."  It is short, but it is sweet!


"Hark - Newton's Second Law of Motion":
Newton’s second law of motion,
Describes how objects accelerate,
Sigma f equals ma,
That is what helps us to say.

That the intensity of a force,
Depends upon the mass of course.

The cause and effect linked in a definite way,
That is what this law can say,
Understanding bodies moving away,
The second law now saves the day.

Reflection: Newton's First Law of Motion

During this lesson about Newton's First Law of Motion, I have learned numerous concepts which are expanded upon in the following Glogster.  The Glogster contains information about some of what I have learned about this lesson, what I have found difficult to understand, my problem-solving skills, and some connections between the learned concepts and real world situations.

This Glog gives a brief overview of motion in general, helping to describe the development of projectile motion at an angle.

Content: The Night Before Christmas - Physics Style

In this Glog, you will see a remix of the poem "The Night Before Christmas" in a physics point of view.  The equations in the ornaments to the side of the poem are equations used when working with objects in projectile motion at an angle above the horizontal.  The "Finding Components" equations discuss how the find the x and y components of a velocity if the have the resultant velocity.  The second set of equations named "Position Components" discusses how to find the range and height of a projectile if you have the time and the original component velocities.  The last set of equations named "Velocity Components" discusses how to find the component velocities of an object at any point in time if you have the original velocities and time.
